我们这儿好像没有这个选项。我的意思是 strategic voting，尽量让自己的一票有效。见下：

"Strategic voting is classically defined as "voting for one's second preferred option to prevent one's least preferred option from winning when one's first preference has no chance." Voters want their votes to be effective, and casting a ballot that will have no influence on an election is undesirable--therefore, some voters cast a strategic ballot when they decide it is useful.
